This is an excellent beginning installment. At around 930 kindle locations, it is short but there's plenty of substance. This installment is the brothers being kidnapped and stops just shortly after their kidnapping and processing, so we don't get much about the Cartel other than that they are a slave ring. There's also no upturn to the story yet - this installment is all dark rapey violence.

Strangely, this did not leave me twitchy for book 2, though I do want to read it, and am happy book 2 is out in a few days. I still wish this would have been released altogether...
